The informativeness of domestic and foreign investors’ stock trades: Evidence from the perfectly segmented Chinese market

This paper uses the perfect market segmentation setting in China's stock market to compare the information content of the stock trades of domestic and foreign investors. We study 76 firms that issue both A-shares (for domestic investors) and B-shares (for foreign investors) and compare the price discovery role of the two segmented markets in China. Before Feb 19, 2001, the A-share market led the B-share market in price discovery, as the signed volume and quote revision of the A-share market had strong predictive ability for B-share quote returns, but not vice versa. After Feb 19, 2001, because some domestic investors were allowed to invest in the B-share market, we find evidence for a reverse causality from the B-share to the A-share market. Nevertheless, the [Hasbrouck (1995). One security, many markets: determining the contributions to price discovery, Journal of Finance 50, 1175–1199.] information share analysis reveals that A-shares continue to dominate the price discovery process.     

Regulation Change and Volatility Spillovers: Evidence from China's Stock Markets

This paper investigates the structural changes of volatility spillovers between Chinese A-share and B-share markets induced by a regulation change on February 19, 2001, that allowed Chinese domestic investors to trade in the B-share market. The empirical results of the study, using high-frequency intraday data collected from a sample of seventy-eight firms issuing both A-shares and B-shares and employing a bivariate generalized autoregressive conditional heteroskedasticity (GARCH) model, show that after the regulation change, the volatility in A-shares increases the volatility in B-shares, thus increasing the risk of the whole market, whereas the latter reduces the former, thus reducing the risk of the whole market. A further investigation of the determinants influencing these structural changes shows that the following factors can encourage structural changes that reduce overall market risk: government ownership, institutional ownership, firm size, B-share proportion, and market-to-book ratio. Conversely, the following factors can encourage structural changes that increase overall market risk: dual roles of chief executive officer and chairman and the joint effect of firm size and B-share proportion.     

Stock Returns and Volatility under Market Segmentation: The Case of Chinese A and B Shares

In most countries where firms list separate shares for trading by foreign and domestic investors, the prices of the foreign shares tend to be higher. In China, the reverse tends to be true. In this paper, we would like to focus on the information content in lagged premiums of Chinese A over B traded shares. The lagged premiums are found to have certain predictive power over the future returns and volatility of both A and B shares, with some interesting patterns. Specifically, an increase in the premium ratio of A shares will be followed by a rise in the return of A shares and a fall in the return of B shares. It is found that both of the investors in Chinese A- and B-share markets reveal positive feedback trading behavior. Moreover, the liquidity and information availability will affect the magnitude of such behavior especially in B-share markets. By using multivariate GARCH model, it is also demonstrated that the unexpected changes in the premium ratio of A-share price over B-share price contribute to the return volatility of both A shares and B shares. These patterns may provide foundations for the development of pricing models for equity shares under market segmentation.     

Stock price reactions to earnings announcements: evidence from Chinese markets

We examine the stock price reactions to changes in earnings per share (EPS) in the Chinese stock markets. We find that domestic A-share investors do not correctly anticipate the changes in earnings and fail to adjust new earnngs information quickly, but international B-share investors can predict earnings changes better than A-share investors. As a result, abnormal returns (ARs) can be obtained by trading on the earnings information, but for A shares only. An explanation is that most A-share holders are individuals with short-term investment horizon while most B-share holders are large institutions that trade on more detailed and accurate financial information not immediately available to A-share holders.     

The Post-Issue Market Performance of Initial Public Offerings in China's New Stock Markets

In this paper, we investigate the post-issue market performance of initial public offerings (IPOs) in China's new stock markets. Our analysis focuses on whether and how institutional features unique to China differentially affect IPO performance. These features include the existence of dual-class shares for the same underlying firms (A-shares issued to domestic investors and B-shares issued to foreign investors) and the unusually long time lag between the offering and listing dates. Our sample consists of 277 A-share and 65 B-share IPOs that were listed on China's new stock markets during the 1992–1995 period. Our study has a number of interesting results. First, A-share IPOs are much more severely underpriced during the initial return period than B-share IPOs. Second, B-share IPOs underperform A-share IPOs (and the market) during the post-issue periods for up to three years. Third, the results of multivariate regression analyses strongly suggest that economic factors determining the post-issue performance of IPOs differ across the A-share and B-share samples.     

Value relevance of accounting information: Evidence from an emerging market

Without making any distinction of the applicable accounting standards, this paper investigates, firstly, the value relevance of accounting information from 1999 to 2012 in different segments of the Chinese stock market. This investigation includes A-shares, prepared under Chinese Accounting Standards (CAS) for domestic firms; B-shares, prepared under either the International Accounting Standards (IAS) or International Financial Reporting Standards (IFRS) for both domestic and overseas firms; and H-shares prepared under either the IAS or Hong Kong GAAP for Hong Kong and overseas firms. Then, the paper examines whether or not the converged IFRS with CAS, applicable from 2007 onwards, is more value relevant when compared with prior to the 2007's standards (CAS, IAS, Hong Kong GAAP for A-share, B-share, and H-share markets, respectively). Based on 34,020 firm-year observations and after controlling for industry- and year-fixed effects, the findings suggest that accounting information is value relevant with A- and B-share markets, while it is partially relevant with the H-share market. The paper finds that the converged IFRS with CAS is more value relevant in A-shares and B-shares and it is partially more value relevant with the H-share market. These findings have implications for both policymakers and investors since they provide further empirical evidence for the current policy procedure which harmonizes local GAAP with IFRS.     

A comparison of value relevance of accounting information in different segments of the Chinese stock market

This paper investigates the difference in the value relevance between the accounting information prepared and audited under the Chinese GAAP for A-share investors and under the international accounting standards (IAS) for B-share investors in the Chinese stock market. The study reports three primary findings. First, accounting information influences the pricing process in both the A-share market and the B-share market. Second, the accounting information in the B-share market is more value relevant than that in the A-share market, as expected. Finally, the value relevance level of accounting information in the A-share market was low in earlier years, peaked in 1996, and then decreased due to changes in the disclosure environment. However, the value-relevance level of accounting information in the B-share market had no substantial changes. Using a constant sample, control variables on firm features, and measures of traders' behavior, we obtain robust results. These findings have implications for policymakers on recent moves toward replacing local GAAP with the IAS.     

Market liberalization within a country

China's B-share market, which used to be restricted to foreign investors, was partially opened up in February 2001 to Chinese local investors. We take this as a controlled experiment in cross-border trading on a small scale. We find mild but positive effects on the B-share market, with higher volumes, lower levels of volatility, lower bid–ask spreads and more liquidity after liberalization. Between A- and B-shares, price disparities narrowed; the correlation and the co-integration relationships became stronger; and the flow of information became more balanced. More new individual investors entered into the B-share market without crowding out existing institutional investors. Even though the liberalization measure is partial and one-way, it has helped to improve the quality of the B-share market, and our results lend no support to the popular claim that liberalization does nothing but help the existing foreign shareholders to cash out.     

The effect of market segmentation on stock prices: The China syndrome

China has an A-share market that is open only to local investors and a B-share market that is open only to foreign investors. Contrary to what has been observed in other markets with a similar segmented structure, the China B shares trade at a discount relative to the A shares. We show that the phenomenon can still be explained by basic economic principles. Specifically, the existence of the H-share and the “red-chip” markets in Hong Kong provide good substitutes for the B-share market. We find that when more H shares and red chips are listed in Hong Kong, the B-share discount becomes larger. This is consistent with the model of differential demand elasticity proposed by Stulz and Wasserfallen (Stulz, R., Wasserfallen, W., 1995. Review of Financial Studies 8, 1019–1057).     

Empirical analysis of dynamic correlations of stock returns: evidence from Chinese A-share and B-share markets

This paper examines the dynamic correlation structure between A-share and B-share stock returns based on three different measures of correlation coefficients. Testing the models by employing daily stock-return data for the period from 1996 through 2003, we reach the following empirical conclusions. First, the correlation coefficients between A-share and B-share stock returns are time varying. Second, the dynamic path of the correlation coefficients indicates that the correlation coefficients are significantly correlated with the trend factor. Third, there is a substantial spillover effect from the Asian crisis to Chinese stock-return dynamic correlations. Fourth, the evidence suggests that the time-varying correlations are significantly associated with excessive trading activity as measured by excessive trading volumes and high–low price differentials. Fifth, the correlation between A-share and B-share markets has increased since the relaxation of the restriction on B-share market investments by domestic investors.     

Foreign ownership and auditor choice

We take advantage of the unique institutional background of the B-share stock market in China to explore the impact of foreign investors on auditor choice. Our results show that the percentage of B-share firms audited by Big 4 auditors has decreased with both economic and statistical significance since the segmented B-share market was opened to domestic investors in 2001. We find that the negative effect of opening the B-share market on demand for high audit quality is more pronounced for firms with greater decreases in foreign ownership and for firms with strong incentives to be opaque, such as those in a weak institutional environment, firms with more “other receivables,” firms with more related-party transactions, and firms with political connections. Additional analysis shows that our results are not driven by the concurrent decline in capital-raising activities in the B-share market.     

Value relevance of international accounting standards harmonization: Evidence from A- and B-share markets in China

Applying both the price-levels model and the lagged-price-deflated returns model, we investigated the incremental value relevance of the reconciliation of accounts from the Chinese Accounting Standards (CAS) to the International Accounting Standards (IAS) by those Chinese listed companies that have simultaneously issued A-shares and B-shares. In addition, we examined the usefulness of accounting numbers (earnings and book values) and their value relevance to the A- and B-share markets in China. The study finds that earnings and book values of owners’ equity determined under CAS are more relevant accounting information for the purpose of determining the prices of A- and B-shares. The CAS-based earnings changes were reflected in stock returns in the B-share market, while the CAS-based earnings were closely associated with stock returns in the A-share market. However, the study found that the reconciliation of earnings and book values from CAS to IAS basis is partially value-relevant, mainly to stock prices in the B-share market, while the earnings reconciliation is generally not value-added to stock returns in either the A- or the B-share market. The study results suggest that accounting numbers based on domestic accounting standards, in contrast to IAS, are more value-relevant in the Chinese stock market at present.     

Long-run equilibrium, short-term adjustment, and spillover effects across Chinese segmented stock markets and the Hong Kong stock market

This paper adopts a novel FIVECM-BEKK GARCH approach to examine the bilateral relationships among the A-share and B-share stock markets in China and the Hong Kong stock market. The evidence shows that these stock markets are fractionally cointegrated. Analyses of the spillover effects across these markets indicate that the A-share markets are most influential. The relaxation of government restrictions on the purchase of B shares by domestic residents accelerates the market integration process of A-share markets with the B-share and Hong Kong markets. The effects of the Asian crisis on the stock-return dynamic correlations vary across these markets.     

Market Segmentation and Information Asymmetry in Chinese Stock Markets: A VAR Analysis

This study examines the market segmentation and information asymmetry patterns in Chinese stock markets. The recursive cointegration analysis confirms that each of six markets is not linked with other markets in the long run. Further, the result from data‐determined forecast error variance decomposition clearly shows that foreign investors in the Shanghai B‐share market are better informed than Chinese domestic investors in two A‐share markets and foreign investors in Shenzhen and Hong Kong markets over time. The finding challenges a widespread assumption of less informed foreign investors in the literature, but suggests that foreign investors could be more informed in emerging markets.     

A corporate governance explanation of the A-B share discount in China

B-shares listed in China are traded at substantial discounts to their corresponding A-shares although they have identical rights. We offer a governance explanation and suggest that relative to domestic investors, foreign investors care more about a firm’s governance quality. Results are supportive, as the B-share price discount is higher for firms that have weaker governance characterized by 1) higher ownership concentration, 2) ineffective boards with a higher proportion of directors appointed by the parent company, 3) lower dividend payouts, and 4) higher levels of information asymmetry.     

CROSS-AUTOCORRELATION BETWEEN A SHARES AND B SHARES IN THE CHINESE STOCK MARKET

Listed companies in China, upon meeting certain requirements, can issue two types of shares: A shares and B shares. Local investors in China can only buy and sell A shares, while foreign investors can only buy and sell B shares. We argue that foreign investors may receive news about China faster than domestic Chinese investors because of information barriers in China. Since foreigners participate in the B-share market, the price movements of B shares should reflect the common information that the foreigners have. Rational A-share investors can therefore condition their trading decisions on the previous price movements of B shares. As a result, returns on B shares should lead the returns on A shares. Using daily prices of A and B shares, we demonstrate that returns of B shares are correlated with those of A shares and that this correlation depends on the information transmission mechanism at work. The pattern of the asymmetric cross-autocorrelation is robust to the inclusion of lagged realized returns and trading volumes.     

Do foreign institutional investors destabilize China’s A-share markets?

This paper investigates the effect of foreign institutional investors on the stability of Chinese stock markets. Previous literature views this investor group as destabilizing feedback traders. We use the abolition of ownership restrictions on A shares as a natural experiment. There is strong evidence that foreign institutions have a stabilizing effect on Chinese stock markets and contribute to market efficiency. This finding is robust across exchanges, sample periods, size quintiles and alternative model specifications. By contrast, domestic investors appear to engage in positive feedback trading. Our results have important implications for market regulation.     

Asset pricing in China's domestic stock markets: Is there a logic?

China's stock markets have grown rapidly since their inception and have become an increasingly important emerging market for international investors. However, there are few systematic studies on how asset prices are formed in Chinese domestic equity markets; popular financial media even depict the market as irrational. In this paper, we study the asset pricing mechanism in the nascent Chinese stock markets, with the objective of identifying variables that capture the cross-sectional variation in average stock returns. We focus on the effects of various market imperfections in China. We find that while the market risk (beta) is not priced, there is a significantly negative relationship between firm-specific risk and expected returns. Chinese investors are willing to pay a significant premium for more liquid stocks or for dividend-paying stocks. Furthermore, investors value local A-shares more if there are offshore counterparts (e.g., B- and H-shares) for foreigners, implying that a Chinese firm with a foreign shareholder base has a lower cost of capital, ceteris paribus. Lastly, as with U.S. and other mature markets, firm size and the book-to-market ratio are systematically related to stock returns. Given market imperfections, stocks are priced rather rationally in China, despite the widespread perception to the contrary.     

Who influences the fundamental value of commodity futures in Japan?

We present evidence on the asymmetric information content of six investor groups' transactions in the gold, platinum, gasoline and rubber futures markets on the Tokyo Commodity Exchange. Microstructure theory suggests that traders with superior information regarding the efficient price should be more profitable in the long run. We find that foreign investors have the greatest influence over the efficient price in the gold market, domestic retail investors in the gasoline market and domestic investment funds in the platinum and rubber markets. Differences in the relative influence of investor groups over commodity futures are likely to reflect the degree of contract homogeneity and associated market liquidity. Foreign (domestic retail) investors have larger information shares for the homogeneous liquid (heterogeneous illiquid) contracts than for the heterogeneous illiquid (homogeneous liquid) contracts.     

Corporate governance and market segmentation: evidence from the price difference between Chinese A and H shares

This paper empirically examines whether the price difference between Chinese A shares, which are traded in the domestic market, and their matching H shares, which are traded in the Hong Kong market, can be explained by firms’ corporate governance characteristics. We find that the A- to H-share price premiums are higher for firms in which the controlling shareholders and corporate insiders have greater potential to expropriate wealth from outside investors. This result is robust when we use a variety of corporate governance variables specific to listed Chinese companies to explain the A-share price premiums and when we control for differences between domestic and foreign investors in required returns, degree of speculative trading, liquidity, information, and demand elasticity. Our findings highlight the important role of corporate governance in explaining the price difference in segmented stock markets.
